Inventor: JUAN R MARUDONEIDO
IPC: G03F1/00
Filed: 1997-09-01
Abstract: PROBLEM TO BE SOLVED: To provide a pellicle which is placed between an X-ray mask and an exposed wafer, in order to prevent the X-ray mask from being contaminated and to prevent the contact of wafer with X-ray absorbing substances. SOLUTION: The pellicle is thin enough to enable X-ray exposure through the required gap between a mask and a wafer, furthermore, sufficiently durable, replaceable, solid and has a film 11 which is so strong against X-rays that it can be used in X-ray lithography. The film is so far separated from an X-ray mask that the film is out of contact with the pattern of absorption material 15 on the X-ray mask 12. The pellicle also has its supporter 12, so that the X-ray mask pellicle can be attached replacebly to the X-ray mask by installing the film 11 on the supporter. Further the pellicle has a supporting ring 13 on which the X-ray mask, the X-ray pellicle supporter, and the X-ray mask pellicle are set.

Title: Method and circuit for calculation of approximate value of logarithm
Inventor: BOKU HEICHIYURU
IPC: G06F17/17
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To minimize the error of the approximate value by using a function that has a characteristic similar to that of the logarithmic curve to correct the error caused in the calculation of the approximate value. SOLUTION: An error correction circuit consists of a multiplier 10, an adder 12, a shifter 14 and an adder 16. The multiplier 10 multiplies both input signals (x) by each other and outputs x<2> . An adder 12 adds the inverted signal (-x<2> ) of the output signal x<2> of the multiplier 10 to the input signal (x) and outputs a signal (x-x<2> ). The shifter 14 serves as a 2<2> shifter which shifts the value smaller than a decimal point of the signal (x-x<2> ) of the adder 12 to the right by 2 bits and outputs a signal (x-x<2> )/4. Then the adder 16 adds the signal (x) to the output signal (x-x<2> )/4 of the shifter 14 and outputs a signal ((x-x<2> )/4)+x. Thus the log approximate value is calculated. These multiplier 10, adder 12, shifter 14 and adder 16 can be mounted in both hardware and software.

Title: Ac feeding distance relay and suppression of its unnecessary operation
Inventor: TAKAHASHI YOSHIO
IPC: H02H3/40
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To prevent the unnecessary operation by the exciting rush current of a train even at the time of high load by suppressing the unnecessary operation by distance-element operation, which can occur by the exciting rush current, in accordance with the judgment based on the second higher harmonic wave component detected from the exciting rush current. SOLUTION: In a feeding classifying station SP, a CT 41 is provided on a line 38. The output of the CT is inputted into a second-higher-harmonic-wave detector 42. When the second higher harmonic wave exceeds the specified value with respect to a basic wave, the operating signal of the detector 42 is outputted. This operating signal is transmitted to a receiving part 45 in a transforming station SS through a high-speed transmitting path 44 from a transmitting part 43 in the feeding classifying station SP. The receiving part 45 inputs the operating signal into a distance relay 46 for AC feeding when the operating signal is received.  Here, the unnecessary operation is prevented based on whether the signal is the 2f lock signal by the higher harmonic wave detected in the main body of the AC feeding distance relay in the transforming station SS or the operation signal by the higher harmonic wave detected in the second higher-harmonic-wave detector 42 in the feeding classifying station.

IPC: H03H9/64
Filed: 1987-09-21
Abstract: PURPOSE:To obtain a desired impulse response by making a pitch of a comb-line electrode constant, and varying the width of each electrode. CONSTITUTION:Since an acoustic reflection element 6 exists in a period B, it is required to make the electrode width narrower than lambda0/8 to make the phase velocities V1, V2 of the sections A, B coincident with each other. In selecting the width of the air gap 5 at the section B as lambda0/8 and the width of the electrode 4 as lambda0/8 (alpha is selected as 0<alpha<1), and selecting so as to have the relation of V1=V2, the phase velocity between the sections A, B is matched. Thus, the phase speed in the exciting direction of the surface wave of the surface acoustic wave is decreased. Thus, no distortion is caused to the frequency amplitude characteristic and the group delay characteristic and a desired impulse response is attained.
